How do you fix frozen air lines?

Tap the brake pad ( metal portion of the pad, dont break/pound the pad itself) with the hammer. Make sure tractor brakes are on, trailer brakes off...dont get run over here. If the problem is the spider valve/proportioning valve or a bad pancake you're doa till service comes.

 

I"m a little confused.

The title says frozen air lines, but you all are suggesting frozen brake shoes. So which is it? LOL

Don't worry about the gauges. If you push the handles in and hear air rushing through the system. The lines aren't frozen. If nothing happens when the handles are pushed in. THEN you've got ice somewhere blocking air from pressurizing.

If you hear a leak, It's probably a frozen valve not shutting off to pressurize the system.

5 pound sledgehammer works really well just make sure you hit the brake drum and not the break or other parts especially your head, just be real careful

 

Okay, try this...red knob still in.

On the suspect cylinder, at the back, there's a little rubber dust boot. There should be a cage bolt on the the side of the brake chamber. If it's not one, check the chamber on the other side for the cage bolt. Remove the rubber dust boot and insert the cage bolt. Turn it slowly and press. You will feel it drop into a slot. You will not be able to turn the cage bolt by hand if it's in the slot. Take a wrench and turn the bolt clockwise. What it will do is cage the big spring for the parking brake and should allow you to move. Tap the drum now. You will still have service brakes but lose one of your parking brakes. This will allow you to get to a shop and have them replace the brake chamber.

 

One good indication if air lines are frozen... Trailer as been sitting for a month right?

Do you have any air in the suspension? If not, most probably frozen air lines, or valve in the tank.

Best bet is alchool in air lines, hammer, pressing, (with red button pushed in)

Its easy to see if a brake is frozen in drum or not, dont forget to check the top pad too, lower pad may be release but top pad might still be frozen in place.

As for the air leak, try checking if any valves are not tight enaugh.

 

If you know your going to be dropping a trailer and have been running in snow or rain,and the temps will be dropping,use just your trailer brakes to heat them up good just before you get to your destination.

That way all the water will hopefully be gone when you drop the wagon.
This will work most times unless the under carriage is totally snow covered..

And kudos to you for not dragging the trailer with locked up wheels.
